Patent JP-S5540270-A (JP)
Title: Inertial pump
Inventor: OOTA KEIKICHIROU
IPC: F04D29/18
Filed: 1978-09-16
Abstract: PURPOSE: To provide a motive machine which has a small size, a high capability and no internal leakage and is easy to machine, by utilizing the motion of a scull of a boat.  
     CONSTITUTION: When blades 5 are revolved around a shaft 6 almost in contact with the inside surface of a casing 5 by a prime mover connected to a shaft coupling 7, water introduced through a suction port 8 flows in a direction P and goes out of an outlet port 9 to cause a thrust. When pressure applied to the left end of a valve 10 through a dynamic pressure measuring section including a pilot pressure transmission passage 11 decreases, the valve 10 is opened by a spring 13 to return water of the outlet port of a diffuser from the valve 10 to the inlet side of the blades 5 through a bypass to eliminate an adverse effect based on the phenomenon that the flowing speed on the intermediate part of each blade 5 would fall below a prescribed level and water would be revolved together with the blades. When the pressure of a pressure outlet port 16 is high, valves 14, 17 are closed by pressure applied to their left ends.

Title: Semiconductor device
Inventor: SANADA TSUYOSHI
IPC: H01L21/8222
Filed: 1980-08-19
Abstract: PURPOSE:To obtain a high-accuracy T<2>L by aligning the electrode leads of compound semiconductor elements to ensure even formation of a Schottky barrier simply by the replacement of individual electrodes under limited influence of parastic resistance. CONSTITUTION:A collector 62, bases 63 and 64, a collector connection layer 65 and emitters 71 and 72 and 73 and 74 within the bases 63 and 64 are formed electrically separated from each other on an SiO2 film 67 over an Si substrate 61. Simultaneously with collector and emitter electrodes, an window is etched through the collector 62 facing the bases 63 and 64 in such a manner as to include a part of the bases to attach metal electrodes thereto. The electrode 69 forms a Schottkey barrier on the collector 62. Therefore, the parastic resistance RD shows its minimum in the electrodes 73 and 74 while its maximum in the electrode 71. As compared with the previous art, this can reduce the parastic collector resistance between emitters thereby enabling marked curtailment of the input current while deep saturation between the bases and the collector with respect to the input voltage at a low potential level.

Filed: 1992-05-07
Abstract: PURPOSE:To obtain the effect similart to that of an expensive skew-magnetized yoke by combining a low price straight magnetized yoke and an axial double- pole magnetized yoke.

Filed: 1979-09-06
Abstract: PURPOSE: To prevent reflection of signal pulse by inserting resistance 2R in parallel with a connection point of characteristic impedance R of transmission line on the signal-generatng side with characteristic impedance 2R on the detection side.  
     CONSTITUTION: When super high-speed pulse light is radiated into photoelectron emission cathode 6, super high-speed electric pulse is generated at the open end of transmission line composed of by-pass 2 and support rod 4. Electric pulse is transmitted to coaxial transmission line for characteristic impedance 2R consisting of outer conductor 10 and inner conductor 11 and resistor 9 for resistance 2R from coaxial transmission line for characteristic impedance R composed of by-pass 2 and support rod 4 through coaxial transmission line for characteristic impedance R made up of metal container 8 and support rod 4. In this case, input impedance for the parallel circuit becomes R. Consequently electric pulse does not generate reflection at these contact points. Under this constitution, reflection of the signal pulse can be prevented.

Filed: 1978-09-20
Abstract: PURPOSE:To accurately measure the ultraviolet ray absorption of specimen gas in high temperature state by heating a light absorption cell at high temperature. CONSTITUTION:Cell heating heater 113 is wound on a light absorption cell 110. The gas temperature in the cell 110 is set at approx. 200 deg.C. under PID control of a temperature controller 114. A flue exhaust gas is continuously introduced into the cell 110. When ammonia gas is accordingly mixed with the exhaust gas, ammonia gas absorption spectrum is focused in the vicinity of an outlet slit 125. When  the slit 125 is vibrated to wavelength-modulate it, the light reaching the light receiving surface of a photo electric multiplier 126 obtains light intensity modulation signal of the amplitude proportional to the ammonia gas concentration. A photo electric multiplier 126' provides a light intensity modulation signal of the amplitude proportional to the sulfur dioxide concentration. Thus, an output proportional to the ammonia gas concentration is obtained through a function generator 300 and subtracting circuit 400, and displayed on a display unit 500.
